Refactor security group show to use SDK

Refactored the 'os security group show' command to use the SDK
when neutron is enabled, but continue to use the nova client
when nova network is enabled.

Added a release note for the change in security group rules output
due to Network v2. The column names remain unchanged to maintain
backwards compatibility.
